| titleOfInvention | Manufacturing method of urethane resin |
| abstract | An object of the present invention is to provide a production method in which a molecular weight can be controlled even when the carboxyl group content is high, and a urethane resin can be obtained by stabilization without causing gelation. A method for producing a urethane resin (A) by reacting a polymer diol (a), a diol (b) having a carboxyl group and a diisocyanate (c), wherein (a), (b) and ( c) has a boiling point of 30 to 80 ° C., dissolves the urethane resin (A), conducts a urethanization reaction in a solvent (B) inert to isocyanate, and the NCO% of the urethane resin (A) is 3%. When it becomes the following, it is a manufacturing method of the urethane resin (A) characterized by adding 1 to 5 weight% of solvent (C) with respect to the weight of a urethane resin (A). Solvent (C): An aprotic polar solvent or polyalcohol having a solubility parameter of 11 to 20, which dissolves the urethane resin (A) and is inert to isocyanate. [Selection figure] None |
